Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed December 13,1905. Serial No. 291,627.

To all whom it may concern:

Be it known that I, LORENZO D. TUCKER, a

' citizen of the United States, residing at Fernando', county of Los Angeles, State of California, have invented and discovered a new and useful Improvement in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in cultivators; and the objects of my improve-' ment are, first, to provide an agricultural implement having one or more cultivator-blades and a wheel attached to the frame of the cultivator for facilitating the movement of the cultivator when in use.

' The invention consists, essentially, in the construction, combination, and arrangement of the several parts, as will be hereinafter described in the specification, shown upon the drawings appended hereto, and specifically pointed out in the claims made a part hereof.

I attain these objects by the construction and mechanism illustrated in the aocomp anying drawings, in which Figure 1 is a view in elevation of parts of my improved implement, portions thereof shown in full lines and other parts thereof illustrated in dotted lines. Fig. 2 is a plan view of the handles of my improved imple ment, portions thereof broken away, the pushing breast piece, the furrow marker, parts thereof shown in full and portions thereof in dotted. lines. Fig. 3 is a view in elevation of the pushing breast-piece shown in full and dotted lines, secured to the frame, the handles of my improvement,*the furrowmarker pivoted to the frame and parts of the frame, the other portions thereof broken away. 'Fig. 4 is a view in elevation of portions of my improvement, parts thereof broken away, the plows, cultivator-blades, and harrow-teeth shown connected there with. Fig. 5 is a view in elevation of portions of my improvement, parts thereof broken away, the plows, cultivator-blades, and barrow-teeth shown connected therewith. Fig. 6 is a view in elevation of my improvement, parts thereof broken away, showing the plows and cultivator-blades connected therewith. Fig. 7 a is a view of the plate to which the harrow-teeth are connected and by means of which the harrow-teeth are secured to the frame of my improved implement. Figs. 7 and 8 are plan views of my improved implement, showing portions of the frame and wheel, other portions thereof broken away, the plows and cultivator-blades secured to the frame; and Figs. 9 and 10 are plan views of the rear portion of my improved implements, showing portions of the frame 1 and wheel, other parts thereof broken away, illustrating the plows, cultivator-blades, and harrow-teeth secured to the frame.

Similar reference numerals, letters, an characters refer to'like parts throughout the several views of the drawings.

The numerals 1 1 denote the upper members or legs of the angular side pieces of the frame A, and the numerals 2 2 refer to the lower members or legs of the said angular side pieces of said frame A, the said upper and lower members of the frame A being preferably made in one piece, and at the apices or junctions of the said members or legs 1 1 and 2 2 of the said side pieces of the frame A the axle 3 of the wheel 4 is provided with bearings 5 5, and upon the extended ends of the axle 3 on the outside of the frame A the draft-hooks 6 6 are secured by means of nuts 7 7. To these draft-hooks 6 6 the tugs or traces of the harness of a horse or horses are attached whenever required to draw the com bined plow, cultivator, harrow, and seeder from place to place.

The curved end pieces 12 12 of the frame A are fastened at their upper ends to the upper ends of the members or legs 1 1 of the frame by means of the headed screw-bolts or rivets 13 13, as illustrated upon Figs. 1, 2 and 3 of the drawings, and the lower ends of the curved end pieces 12 12 are secured to the rear ends of the members or legs 2 of the side pieces of the frame A in like manner by means of headed screw-bolts or rivets 14: 1 1, as shown upon Figs. 1, 4, 7, 8, 9, and 10 of the drawings. The said members or legs 2 2 of the side pieces of the frame Afor the greater portion of their length extend parallel with each other, as illustrated upon Figs. 1, 4, 5, 6, 7 8, 9, and 10 of the drawings, and near the rear ends of said members or legs 2 2 are provided with angular inturned portions 15 15, and the end portions 16 16 of the said members or legs 2 2 again extend parallel with each other, forming a narrow space 17 therebetween, in which the beams 18 and 19 of one of the plows 18 and 19, respectively,

ICC

are fastened (one of said plows being smaller than the other and arranged in parallel lines with each other) by means of the headed screw-bolts 2O and nuts 21 21, as shown in the figures of the drawings. A doublemoldboard plow may be used in place of the plows 18 and 19.

The plows 29 29 (shown upon Figs. 1 and 6 of the drawings) and the cultivator-blades 25 25 have their shanks 26 26 bent at right angles to the members or legs 2 2 of the frame A, as shown at 27 upon Figs. 1, 4, 5 and 6 of the drawings.

All the shanks of the plows 29 29 and all of the shanks of the cultivator-blades 29 29 are secured to the members or legs 2 2 of the frame A by means of slotted disks 30 30, as illustrated upon Figs. 1, 4, 5, 6, and 10 of the drawings. These slotted disks 30 30, bolted to the beams of all the plows and cultivatorblades secured to the members 2 2 by means of rivets or screw-bolts 31 31, permit the plows and cultivator-blades to be thrown in the elevated position, as shown upon various views of the drawings, or in the position to turn the earth, as illustrated upon Figs. 1, 6, and 10 of the drawings, the headed bolt 32 being arranged in the slots 33 33, the said slots 3333 being moved upon the said bolts 32 32 when the plows and cultivator-blades are raised and lowered.

The beams 18 and 19 of the rear end plows 18 and 19, respectively, (shown upon Fig. 7 of the drawings,) have secured thereto slotted disks 3O 30, which are clamped in the space 17 between the extended ends of the members 2 2 by means of headed bolts 32 32.

The harrow-teeth 35 35 (shown upon Figs. 4 and 5 of the drawings) are secured at their front ends to the plate 36 by means of bolts or rivets, the said plate 36 being bent twice upon itself at right angles, as illustratedupon Fig. 7 of the drawings, forming a rectangular opening'in the front free end of said plate, adapted to be secured upon the inturned ends 15 15 of the members or legs 2 2, as illustrated in Figs. 8, 9, and 10 of the drawings.

The handles 40 40 of my improved implement are pivoted at to the curved end pieces 12 12 of the frame A. The front ends of the said handles 40 40 are swiveled at 61 upon pins to the links 62 62, and the said links 62 62 are connected by means of pins 63 63 in slots 64- 64 in the upright members or legs 1 1 of the frame above the journal 3, on which the wheel 4 of the implement revolves. The said handles 40 40 can be raised and lowered, as shown in dotted lines upon Fig. 1 of the drawings, and the asid links 62 62 can also be raised or lowered by moving the pin 63 in the slot 64, the pin 61 bearing against the rear edge of the member or leg 2 of the frame.

The numeral 67 denotes the pushing breast-piece, which is longitudinally extensible, as shown in dotted lines upon Fig. 3 of the drawings. The said pushing breastpiece 67, slida'bly connected to the rod 68, which is swiveled to the cross-head 69 of the frame, as shown upon Fig. 2 of the drawings, is held at any point thereon by the thumbscrew 69. The said improved pushing breastpiece I employ for moving the implement from place to place. The said longitudinallyadjustable breast-piece 67 is secured in place when not in use within the keeper 70, having a. pivoted button 71 (shown upon Fig. 3 of the drawings) secured to the keeper, as shown upon Figs. 1 and 2 of the drawings.

Having been required to divide out of this application the plows, the barrow-teeth, the seeder, and the land-marker, I hereby reserve the right to file separate applications for patents for each of the subjects-matter required to be divided out of this my original application.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, mode of operation, and advantages of my invention will be readily apparent without requirmg further extended explanation.

Various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, and I therefore reserve to myself the right to make such changes as fairly fall within the scope thereof.
